Gated Photochromism in Triarylborane-Containing Dithienylethenes: A New Approach to a "Lock-Unlock" System
Photochromic inactive dithienylethene derivatives appended with 3- or 5-dimesityiboryl-2,2'-bithiophene have been synthesized. Upon fluoride ion-binding, the photochromic reactivity is "unlocked", displaying a novel gated photochromic property.
